Re: Do you run headers ?
Jason
As of now I hooked the spring to the brake line until I can fab up a clip. I figure that I will mount the clip with the brake line clamp. Look at the left side shot, you can see the spring. I will try and get you a shot of the little extension rod tommorrow if I can. Rich Grady was talking about the electric exhaust cutouts. I am to cheap for those... https://www.yenko.net/ubbthreads/imag...ns/naughty.gif Sammies Glad you like'em. Fired the car up https://www.yenko.net/ubbthreads/imag...emlins/eek.gif sounds cool. I have a appointment to get the pipes made in the morning. It's only a few miles, maybe instead of trailering down I will drive.....right past the State Patrol Baracks https://www.yenko.net/ubbthreads/imag...iggthumpup.gif |

Mike,
Nice job on the headers, they look great. Gives me some ideas https://www.yenko.net/ubbthreads/imag...ns/naughty.gif. Love the safety wire job too. Phil Woj. |

Re: Do you run headers ?
I found a great exhaust system that will give you quaility,performance and the appearance of factory installed.Dougs Headers are top of the line 3/8" flange thick tubing and silver ceramic coating.Flowmaster kit all the way out back.Going on 10+ years installed outstanding?

Re: Do you run headers ?
I'm not sure I even get why you pump air headers without a cat behind them?

Re: Do you run headers ?
I've seen the smog systems plumbed into headers in some of the old 1969-70 Hot Rod Magazines for California cars..
I believe it's a strict law out there that you have to run smog on everything, isn't it?? Rich |

Joe,
Those look unreal!! Talk about best of both worlds. I bet that thing sounds as good as it looks. I sent you a PM for the part # of those awesome looking headers!! |
Re: Do you run headers ?
Kevin DeWitte told me that his Berger delivered Dover White COPO had smog with headers from the dealership. He was told that he had to run the smog tubes in order to keep his warranty.

Re: Do you run headers ?
------Paul,,,If you think back there were smog-pumps several years before there were catalytic converters. Back then (68) I remember saying to myself that I would never own a car with a smog pump. That was definetly age and stupidity talking. I also said the same thing when 5MPH bumpers showed up (1973) https://www.yenko.net/ubbthreads/imag...ins/tongue.gif......Bill S |
Re: Do you run headers ?
I can relate to some of those feelings Bill. Funny how things were so cut-and-dry in a young mind.
I think an air pump into an exhaust manifold can be somewhat effective since those cast iron manifolds would act like an oven. With some additional oxygen form the smog pump, those unburnt HC's could be cleaned up. I think with headers there is a significant reduction in cleaning up the HC's because you loose the oven effect. |

Re: Do you run headers ?
Just in case nobody has mentioed them already.I recently installed a set of "header buddies" on my Car.These are replacements for the stock 3 bolt collector redcers that come in the box with most headers.These are reducers that doesnt use a gasket.They have a very slight flanged crimped into the pipe,and a small{maybe 1/8") of pipe that goes into the collector on the header.They come with new 3 bolt flanges as well.I was watching Two Guys Garage one morning and they were giving them props so I decided to try them on my newest project.After I installed them,I called the guy who makes them and told him how great they are.They only cost about $40 for the pair and come in many sizes.I as very impresed.Good luck.

Hello, I am really thinking about installing some headers on my stock 70 LS5 Chevelle. The exhaust manifolds that are on the car are not the right ones and will have to come off at some point anyway. This is a #'s matching style car that is driven just about every weekend. I am not too worried about changing gaskets if needed. Call me crazy, but I love stock appearing musclecars wih a nice sounding aftermarket exhaust along with headers. But I also like the simple and correct look of the factory exhaust manifolds. (I would have to find the correct ones of course..) So my question is this... Who all runs headers on their mostly stock/restored cars? https://www.yenko.net/ubbthreads/imag...lins/beers.gif [/ QUOTE ]A few things to keep in mind. 1-the headers won't add any power that you'll actually feel in the seat of your pants.2-the car will be a bit noisier inside, as sound dissipates out the tubes more than cast iron and will be heard through the firewall.3-because of the sound bleeding through as explained in #2, the exhaust out the rear of the car may actually be a bit quieter as a result |

The headers will allow more air out of the motor which will push more air/sound through the mufflers and out the back. As far as seat of the pants. I am thinking there will be a noticable difference.

[/ QUOTE ]The need for headers by your healthy Lingenfelter may be greater than the LS-5 in question. I was basing my "power" comment on that, from experiences in the past. Also, headers won't move any more air, just more efficiently. All exhaust leaving the exh. valve will eventually find it's way past the iron exh. manifold (where else can it go?). Also, it's known fact that a lot of sound will bleed through the thin tubes of a header, leaving less sound to make the trip to the rear of the car. I've installed a lot of headers yrs ago, when glasspacks were fairly common. It was amazing how many blown out sets got quiet after the header install. Hey, it's just all opinion, and that is mine |
Re: Do you run headers ?
Groucho, I was with you on your previous posts in other threads but don't follow the points made above.
I do agree that some headers can bring noise into the car. I love the sound a of a healthy camshaft ringing the header tubes at idle. |

Re: Do you run headers ?
The LS5 in question is still mild. Its got probably a little bit more than it did from the factory. But still running a Q-jet and cast intake. My fairly healthy comment meant that its not a tired old motor...
Well I am looking for a more aggressive musclecar sound. So you are saying I will have a more agressive sound in general by leaving it as is with manifolds? |

But, as I said, some sound will dissipate through the header tubes themselves. That is a sound I happen to like, but it comes more from the engine compartment area than the exhaust tips. Because of the dissipation of sound from the header tubes,less sound makes it to the tips, usually making it a bit quieter, BUT IMO better in quality. Make sense? In my 1st response, I wasn't trying to talk you out of installing headers. I was just giving you something to think about, so you didn't expect too much |
Re: Do you run headers ?
I disagree that headers don't move more air. They do. Sure, eventually the same amount of air can be moved through a Mcdonalds straw, but headers will move more air that those LS5 exhaust manifolds will, given a specific window of time- say a 1/4 mile pass.
I disagree that the sound out of the back of the car will be quieter with headers. I get you theory that sound is dissapating through the headers so there won't be as much sound to make it out of the exhaust tip. I just disagree. There are several other facotrs at work here. I would think they the rougher surface of the cast iron manifold would deaden the sound more that what audibly leaks through a header, but that is just one unaddressed point. Don't get me wrong, I am fine agreeing to disagree but you asked for some specific points. |

When I was 14 (1969) the guy across the street had a 68 SS 350 Camaro w/4-speed. He put glasspacks on it right after he bought it new. By 69, they were LOUD, and I could hear him 3 blocks away when he was coming home from work. I'd go out there almost every night and hang out with him. One evening, I could barely hear the Camaro, but I heard something. I looked out the window, and it was him. I ran over, and said, hey, why'd you get new mufflers? He told me the only change that day was the installation of headers. MUCH quieter. Probably the most drastic that I've heard, but certainly not the last. Anyway, I came to learn WHY it was quieter. It's fairly difficult to argue with facts |

Its probably coming out a little smoother and faster. Meaning at certain RPM's maybe it is quieter than before. But maybe at higher RPM's it will actually be louder than before. |
